I pushed to a new branch because that commit was just something to test
and probably not to keep. And it turned out as rubbish.

I think you should for now just bypass this precheck and see if sage
builds. I think it should be able to build with gcc 4.9 just fine and
put the right --std=c++11 flags itself.

You can disable the pruner check for fplll by replacing the relevant
bits in debian/pruner/configure.ac by

# FIXME(fplll): Disable check for jessie-backports because it fails with
gcc 4.9
HAS_FPLLL="True"
AC_SUBST(HAS_FPLLL)

Best,
Tobias
